This is a division of application Serial No. 82,979, filed June 1, 1936.

The invention relates to improvements in fluidtight tension ringclosures for metal packing vessels and has for its object to provide asimplified device of this character affording a reliably tight fit ofthe ends of the tension ring and the possibility of adjustment thereof.

In the accompanying drawings:

On the edge of the vessel a and enclosing the packing b, is located thecover 0 of the vessel, provided with a hollow edge, the tension ring dembracing the cover and edge of the vessel. On the ends of the tensionring are secured the closure parts 6, J.

On the closure part c, of one end of the ring, the tension lever h ispivotally mounted at point g with the extension I, which bears againstthe edge of the cover 0. The extension I .carries the tightening member2, which is pivotally mounted at point I. The lever 71. is bent ofi tothe thickness of the closure parts e, f, so that the tightening member 2slides closely over the same. Towards the middle of the cover thetightening member is chamfered in a downward direction over the wholelength and the chamfered edge bears tightly against the closure parts e,f. The engagement projection 3, which is provided at the freelyprojecting end of the-member ,2, and is also made by bending round orturning down the corner, engages selectively in the engaging slots 4 ofthe closure part 1 and at the same time, owing to its hook-likestructure grips under the closure part I in such a way that any pressingdownward is prevented. When engaging in the slot 4, selected inaccordance with the desired degree of tension, the engaging projection 3fits into the whole length of the slot. It is thus made difficult forthe tightening member 2 to be swung down and thus the tension lever 71.is effectively secured against snapping back into the open position. Theholes 5 are intended to receive a sealin wire, (Fig. 3). Fig. 3 alsoshows that in the case of both the largest as well as in the smallesttension position the axes of pull .ra: and z-z form an acute angle withthe tangent y y 0n the side opposite the tension lever h. Fig. 4 shows apartial side view of the tightening member 2, to an enlarged scale, thesaid member being bent at the portion 6 disposed towards the center ofthe cover, in such a way that it also embraces the closure parts e, i,from below. As a result the stability of the closure is increased to afurther extent.- Fig. 5 shows the tension ring closure according to theinvention in the open condition. The surface of the tension member 2 isprovided with advertising matter.

Inthe modification shown in Figs. 6 to 10, the

tensioning of the closure is effected by swinging the lever h towardsthe edge of the cover, in

which case through the bearing of the widened part I of the lever 71.against the edge of the cover, one end of the ring isdrawn toward thevessel edge. At the same time the closure part I isgripped by thetightening member 2 and the other end of the ring is also tightened. Theaxes of pull xx and ZZ, which correspond to the smallest and largesttension position of the tightening member 2, form an acute angle withthe tangent 11-21. applied to the junction point of the ring, in thesame manner as described previously, the apex of this angle lyingopposite the tension lever.

The closure parts e and f are provided with the longitudinal eyes 1 and8 arranged towards the middle of the cover and through which thesecuring pin 9 is inserted in the closed position. The longitudinal eye8 of the closure part c is open at the side towards the edge of thecover,

so that when the lever 71. swings into the open position the limitingpart III of the tension lever projects into the open side of thelongitudinal eye 8 (Fig. 9). On the other hand, the part III, when thesecuring pin 9 is inserted, presses against the latter, so that it isnot possible to open the closure (Fig. 10). The projecting end thesealing wire or the end, if the pin consists the ring is contracted, andmeans for contracting the ring, including a lugat each end of the ring,directed inwardly toward the center of the cover,

a lever pivoted to one lug, a projection on the 1 lever between theinner cover edge and the pivtotal point of the lever and adapted to bearagainst the cover edge so as to draw the end of the ring against theouter edge of the cover,

means pivoted to the lever and engaging with the second lug for enablingthe two ends of t e ring to b drawn together by means of the lev r,

the axis of said means in the closed position intersecting the tangentto the ring at the ju tion point of its two ends in an acute angle onthe side of the junction point removed from the -'lever, an eye on eachof the lugs and a .pin adapted tobe passed through the eyes in theclosed position, the eye on the lug which carries the lever having arecess and the lever having a flat edge which bears against the pinthrough the recess in the closed position and which can swing into therecess when the pin is withdrawn.
